WebThis process is thought to be important for the regulation of gene expression, as miRNAs can alter the expression level of their target genes by preventing the formation of functional proteins. Overall, acetylation of histones, methylation of DNA, and microRNA all play an important role in regulating gene expression in eukaryotic cells. WebHistones are proteins found in eukaryotic cells that package DNA into nucleosomes. Histone binding prevents the initiation of transcription whereas transcription factors promote the initiation of transcription. The most 3' portion (closest to the gene's start codon) of the core promoter is the TSS which is where transcription actually begins.
